Ouyang Ling obviously had already been in contact with the Dan Fang of the Four Turning Qi Pills, and it was even possible that she had practiced it on a regular basis, this kind of Dan Fang was not a top secret, as long as it was a person in the trade union, most of them could come into contact with it.

Luo Tianlin is completely an alchemy novice, and it took half a cup of tea just to look at the Danfang. Although the Danfang provided by the association has a proportion of ingredients, the timing of the fusion of heat and medicinal materials in alchemy needs to be controlled by the alchemist himself.

Of course, Luo Tianlin didn't need these, because his so-called alchemy was to use the breath of Shennong Ding to extract the essence of the medicinal materials, and then combine them into a pill. All he had to do was memorize the amount of each herb needed.

As for the identification of medicinal materials, he handed it all over to Shuxiang, and for the medicinal materials on this continent, except for a few herbs abundant in the Valley of Hundred Flowers, the others were completely ignorant.

At this time, Ouyang Ling had already finished taking the medicinal materials, lit the furnace fire, and began to heat the furnace.

The hot furnace is the first step in smelting medicinal materials, and the purpose is to make the temperature in the furnace equal, which is conducive to the melting of medicinal materials. This step is the most test of the heat resistance and thermal conductivity of the Dan furnace. Dan furnaces that can make the heat distribution more uniform and have a higher temperature tolerance tend to perform better on the melting powder.

Ouyang Ling's Dan furnace was obviously not ordinary, and it had only been heated for less than half a cup of tea, and she had already begun to put the first medicinal herb into it, Qingwu Gen.

At this moment, Luo Tianlin walked unhurriedly to the medicine cabinet and began to take medicinal materials. Soon he weighed all the fifteen medicinal materials used in alchemy and returned to the alchemy table.

There are two ways to make a fire in an alchemy furnace, one is to use external heating, that is, to heat the stove, and the other is to use flint directly in the furnace. Compared with the two methods, the first one has high temperature, strong firepower, and is easy to control. The second is that it is easy to carry and can be used anywhere.

But no matter which method it is, refining an elixir above the green level requires the assistance of internal or spiritual power. It is used to increase and control the temperature in the furnace and adjust it locally.

Refining a green-level fourth-grade elixir theoretically requires the strength of [and body realm], and Ouyang Ling on the opposite side obviously did not reach this realm, but she has her own methods.

I saw her take out a small bottle and pour a pill into her mouth every once in a while. This pill is very familiar to those who practice martial arts, it is the green-level first-grade Huiqi Pill. This is how Ouyang Ling keeps herself always having internal strength to use.

However, there are risks associated with using Huiqi Pill in such a large amount, one is the ability of the meridians to bear it. Although the pill is purer than the aura of heaven and earth, it is not that there are no impurities at all, and the lower the level of the pill, the more impurities. Frequent use of pills and failure to remove impurities in time will lead to obstruction or even damage to the meridians. The second is the loss of mental power, using power that does not belong to you for a long time, and precise control, which is an extremely huge test of willpower.

However, Ouyang Ling's face did not change in the slightest except for the slight sweat on her forehead, and she was still engrossed in controlling the heat.

Even the alchemy master Qi He was a little moved by such a performance, and Zhuge Tian on the side was also worried, as if he could feel the great pain his daughter endured.

Judging by the opponent's performances so far, this is definitely a worthy opponent. Luo Tianlin's face also became serious, and he decided to go all out, so that he could show respect for the alchemist opposite.

Igniting the furnace, because he didn't want to be too earth-shattering, he didn't omit this step, and the medicinal herbs were easier to decompose at high temperatures.

Then Luo Tianlin's next move, but the two alchemy masters present were stunned, and he actually put all the medicinal materials into the alchemy furnace in one go.

"Isn't this Hu Lai! I said Xiao Hong, does this person you brought really know how to make alchemy?" Qi He's face was ugly, and he turned his gaze to Ouyang Hong on the side.

Ouyang Hong was also very helpless in his heart, he didn't expect that this young man who looked extraordinary in bearing really didn't know how to do alchemy.

The different melting order of the herbs will have a great impact on the potency of the final pill and the formation of the pill, which is why the same material ratio will have a very different effect according to different pills.

Even Ouyang Ling, who had already refined to the ninth medicinal material, couldn't help but glance over here.

Luo Tianlin was completely immersed in the melt medicine at this moment, and all the conversations and questions from the outside world were deaf. What he had to do now was to channel the power of the artifact emitted by Shennong Ding into the alchemy furnace, and the power of the artifact was stimulated by his own internal force after entering the artifact space. From this point of view, the use of Shennong Ding projection for alchemy, in fact, is the same as ordinary alchemy, and it also needs a lot of internal force to back it up.

A steady stream of green energy enters the alchemy furnace, and if someone can enter it to watch, they will find that all the medicinal materials are like ice cubes meeting torches, quickly starting to melt, not only that, but the medicinal effect part and the impurity part in the medicinal materials are automatically and orderly separated, and the impurities are deposited at the bottom of the furnace, while the essence floats in the air.

It is also refining green-level four-grade elixir, but Luo Tianlin seems to be at ease, although he has not reached the [and body realm], but the Haotian Baihua Jin in his body has been refined by the phantom of the artifact Haotian Tower, and it has the breath of the artifact, after entering the Shennong Ding space, there is almost no loss in the process of generating the power of the artifact, and the decomposition speed of the power of the Shennong Ding for medicinal materials is far from being comparable to the furnace fire.

In this way, when all the medicinal materials were refined, less than half of the internal force in his dantian was consumed.

Refining is half the success of alchemy, what is needed is a peaceful and continuous output of internal force. And the next Cheng Dan is the other half of success, and it pays attention to instantaneous explosiveness.

Using mental power to control the essence of all medicinal herbs combined, this is Cheng Dan. It not only tests the strength of the alchemist's internal force, but also the strength of his spiritual power.

The strength of the internal force is a necessary condition, and if the internal force does not reach the strength that can compress the liquid medicine into Dan, it will definitely not be able to become Dan. And if the mental power is not enough, you can only give up part of the medicinal liquid and reduce the number of Cheng Dan.

The reason why it is said that spiritual cultivation is more suitable for alchemy than martial cultivation is because they have strong spiritual power, and the number of Cheng Dan is far more than that of martial cultivation of the same level.

Both of them are about to enter the Cheng Dan stage, and at this time, half of the timed incense has been burned, and if they fail, they will not have a chance to do it again.

Everyone present became nervous, but almost no one paid attention to Luo Tianlin's side, including Zhuge Tian. Because everyone thinks that his method of melting medicine has ruined the medicinal effect of the medicinal materials, it is impossible to become a pill again.

Six pairs of eyes stared at Ouyang Ling in unison.

I saw that she swallowed the three Hui Qi Pills in her mouth at the same time, and her face suddenly turned pale, and her whole person trembled slightly, as if she was under tremendous pressure.

"Together!" she opened her mouth to snort, and her hands snapped together. She only heard a "ding, ding, ding" sound in the Dan furnace in front of her, and the furnace began to shake violently.

"Bah!" the lid of the furnace was suddenly rushed open, and two snow-white pills rose into the sky. Ouyang Ling took out a jade bottle and quickly filled it into it.

And just when she finished all this and showed a happy smile on her face, a mouthful of blood suddenly spurted out, staining the snow-white robe on her body red.
